' 7 ATTORNEYS ai'easea To all whom it-mag concern:

. Be it'known that l, JosEri-I BIJUR, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Lighting I Systems'for Automobiles, of whichthe following is a full, clear, and exactdescription,

such as will enable others skilled in the art to'which it appertains tomake and use the same. i

This invention relates tocircuit-varying devices, and with regard to themore specific featuresthereof, to devices of this nature in connectionwith electrical regulating and lighting systems.

One "of the objects thereof is to provide an electrical regulatingsystem of accurate and reliable action. e

Another object is to provide an electrical system comprising .avibratorycircuit-inv terrupter in which practical and automati- Iplication ofwhich will cally acting, means are provided to prevent injury to theparts. 25

Other objects will be in part obvious and in partpointed outhereinafter.

The-invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe apfollowing claims In the accompanying drawing, in which is shown.one of various possible embodiments of this inventionFigure 1 is adiagrammatic plan of a system; Fig. 2 is a sideiele'vation of switchingmechanism, certain parts being removed inorder. to show the constructionmore clearly;-and Fig.- 3

vibrator magnet 12, from which it leads to the coil 13 upon the mainswitch. A voltage coil 14 is wound upon magnet 10 to act normally with acompounding eifect with respect to coil 9 and a secondvoltage coil 15 isprovided upon the magnet 12. The main switch is provided with a voltagecoil 16, and a resistance element 17 is connected in parallel with thegenerator field.

As diagrammatically indicated in Fig. 3 of the drawing, there isprovided at 18 a lamp switch for connecting or disconnecting the lampload with the battery or generator.

Thereis also provided a reversing switch 19 whereby the connectionsbetween thebattery leads and mains 5 and 6 are reversed, and therelation of these switches and connections therebetween is best shown inFigs,

2 and 3 of the drawing. Switch 18 may be i of any desired 'typeand ishere shown as spectively making and breaking connection between thecontacts 21 and 22 connected in the conductor leading from-the batteryto the lamps. It is to be understood that, in practical use, the switch18 preferably takes the multiple contact'form, so as to permit,

inthe case of automobile lighting, for ex; ample, the connection of thetail lamp by itself or the tail lamp and head lights or I The spindle ofthis switch is actuated by a button 23 and is con- ,75 comprising amovable contact 20 which as-' sumes one of .two alternative positions,re-

tinned, as shown at 24, through thebracket 25 upon which the switchesare mounted and terminates in a worm 26. This worm meshes with a wormwheel 27 on the spindle 28- of the revei'singswitch 19. The latter is ofthe well-known type provided with a spindle which, upon being turned,distorts a spring to such a degree that it suddenly snaps a pair ofrelatively insulated short circuiting members out of engagement with twopairs of stationary contacts and into suchposition as to connect thesecontacts in a reverse manner. The details of switches of this nature arewell known and form no part of the present invention, but it may benoted that as the spindle 28 is rotated it intermittently reverses theconnections between the battery 7 and the generating and regulatingsystem. i

Recurring to Fig. 3 of the drawing, it is to be noted that the generalaction of the regulating apparatus is as follows :The

. generator, thus weakening the latter.

this occurring; the inagnet'which has attrac attains sufficient fieldstrength attract its armature against corresponding vibratory the forceor the retracting spring, this shunt will be bro en and the resistance 3thrown into circuit in series with the held of the ed its armature willbe similarly wealiene and the armature retracted against its staoutput.

"tionary contact, thus again coiirpleting the rent permits thedeposition upon one of each pair of vibratory contacts of a minute massof metal whicl interferes mechanicallyand electrically th the action ofthe vibrator. This action also talres place in connection with otherautomatically controlled and frequently operated contacts, as in themain witch, and is harmful such points, although particularly injuriousat the contacting surfaces oil-a regulating vibrator. lit the current bereversed, however, there is a reversal 0" this action which not onlytends to prevent further injury to the contacts, but in a measureremoves that already done. 7 v

The operation of the above-described embodiment of this invention issubstantially asfollows: Assumingthat the generator'be charging thebattery and that the lamp load is thrown on, this manipulation of theswitch 18 acts, through spindle 2%, to turn the spindle 28 throughout asmall angle. It the lamps be turned cit the further rotation of spindle24: will occasion a further move ment of spindle 28 and at a certainpoint after, in this; embodiment, a considerable number of actuationsofthe lamp switch 18., the reversing; switch 19 will be operated and theconnections between the battery and generator system reversed. When thisac-- tion takes place there is a tendency of the battery to dischargeback through the armature circuit and there is an instantaneous surge ofcurrent which may tend to reach a high value, but the reversal of thegenerator fieldwll'l cause thegeneuator to build up Up on current actingthrough coil S) will open the shunt about resis cc 3 by the action ofthe zilarator of magnet 10, thus weahoningthe l and tending-to hinderthe proper pic/li- 7 up of the generator to meet the rc- *ersed battc-yconnections. Under these "ions, however, the'coil becomes of rcve sec.polarity; and a ts diii'ercntially resultant held of the magnet 10 andcausing, the shunt about resistance 3 to close. It ce noted that thereverse of polarity of the coil re,

due the fact that connections reversed and with momentary surge ofcurrent resulting; tllGl'QIlil'Oll'l, the battery will determine thedirection of llow through these. coils rather than the genera thegenerator voltage may th the battc sal, nevertheless, it will drop oilwhen. the aoove rush of current occurs much more quickly than will thatof the battery, due partly to the limitcdoutput of eneroy of which it iscapable and p: tlyto the areal;- ing of the shunt about resistance 8,215above stated. The generator will accordingly build up with reversedpolarity and the flow of current through the several circuits, includingthe shunt about resistance 3, is reversed. The current being reversed,in coil 5 and the generator thus built up, permits this coil to againactcumulatively with respect to coil. 1; and the regulation proceeds as.before.

is to be noted that this reversal is automatically accomplished, in theordinary use oil? the system, by the actuation of the lamp switch, andhence all contacts are eiiectivcly jjii'otected without the need forsupervision. it will-also be noted that by the action the parts asherein set forth, the battery may be connected i any manner found mostconvenient or etucient without interfering with the action oi thegenerating); and regu lating system.
